Iranian Multi-center Osteoporosis Study (IMOS), 2021-2022: the study protocol.

BACKGROUND: This paper presents the protocol of the 4th round of Iranian Multi-center Osteoporosis Study (IMOS), a national survey with the primary objective of estimating the prevalence of osteoporosis and sarcopenia and their risk factors in a representative sample of urban and rural populations. METHODS: The target population of the survey is all individuals ≥ 50 years in Iran. A multi-stage random sampling method has been used in the study. We stratified the 31 provinces of the country into 5 strata based on the distribution of their potential risk factors for osteoporosis and randomly selected one or two provinces from each stratum. Then, we invited 2530 people aged ≥ 50 years recruited in the 8th National Survey of None Communicable Diseases (NCD) Risk Factors (STEPs-2021) in the selected provinces to participate in IMOS. Body composition measurements including bone mineral density, muscle mass, and fat mass are measured through Dual-energy X-ray Absorptiometry (DXA) method using HOLOGIC (Discovery and Horizon) devices; and Trabecular Bone Score (TBS) is measured on the DXA scans using iNsight software. Anthropometric measurement and physical examinations are made by a trained nurses and other required information are collected through face-to-face interviews made by trained nurses. Laboratory measurements are made in a central lab. The prevalence of osteoporosis and sarcopenia will be estimated after applying sampling design, non-response, and post-stratification weights to the data. DISCUSSION: IMOS will provide valuable information on the prevalence and determinants of osteoporosis and sarcopenia at the national level, and the results can be used in evaluating health system interventions and policymaking in the field of musculoskeletal diseases.

Primary Health Care Model for Non-Communicable Diseases Management during COVID-19 Pandemic in the Islamic Republic of Iran.

Background: Given the importance of appropriate response to prevent and manage Non-Communicable Diseases (NCDs), this study aimed to analyze the state of NCDs services at the level of the PHC system during the COVID-19 pandemic and to determine the main strategies. Methods: In this qualitative study, first, the circulars and guides in Iran's PHC system from the beginning of the pandemic to the end of September 2020 were retrieved manually and by searching the internal websites of the Ministry of Health. All documents about decision-making or governance and coordination mechanisms for the provision of NCDs services were enrolled and analyzed. In the second phase, the status of service delivery for major NCDs was presented in a model, and finally, SWOT analysis was used to analyze the situation and determine the main strategies. Results: 25 out of 199 circulars and guides were eligible and analyzed. In the crisis phase, most risk assessment, screening, and diagnosis services for NCDs have been suspended, and follow-up and care of patients with major NCDs were done by telephone. In the reopening phase, the general strategies and strategies to increase capacity and provide delayed care were adopted, and the PHC model of the provision of essential services for the major NCDs was developed in low-risk, intermediate and high-risk pandemic conditions. Finally, 16 main strategies were determined with the approach of integrating and focusing on essential services, considering vulnerable groups and the use of E-health technologies. Conclusion: The results indicate on interruption of NCDs services in the crisis phase while adopting strategies for responding to the pandemic. Revision of the COVID-19 guides with a particular focus on NCDs is recommended.

The Effect of the COVID-19 Pandemic on Non-Communicable Disease Prevention and Management Services in the Primary Health Care System of Iran.

Background: The COVID-19 pandemic has caused significant disruptions in the provision of non-communicable disease (NCDs) prevention and control services in many countries, and there is a concern that it would lead to long-term complications of the diseases. The aim of this study is to assess the changes in the provisions of selected NCD services before and after the COVID-19 epidemic in Iran's primary healthcare system. Methods: In this descriptive-analytical retrospective study, the number of eight NCD services provided during the first 10 months of the COVID-19 pandemic from Feb 2020 to Dec 2020 were compared with the same period in the previous year using the data from the Iranian integrated electronic health record system (SIB) and also the association between the number of deaths due to COVID-19 and a sample of NCD services were assessed using cross-correlation analysis. The statistical analysis was performed in Stata Software v.14. Results: The NCD services have decreased by an average of 18.89% compared to the same period in the previous year; this decline was much more severe at the beginning of the epidemic period (up to 75% in some services) and was greater in physician-provided services than in non-physician services. Also, examining the course of the selected services during this period, a gradual compensation was evident after the initial reduction. Conclusion: The general trend of the selected services of prevention and control of NCDs in the PHC system of Iran within 10 months after the onset of COVID-19 showed a sharp decline and subsequent gradual compensation. Although the process of compensation in some services may be considered somewhat reassuring, in the case of some essential services, more effort and attention to the implementation of programs or compensatory policies seem necessary.

Annual incidence of osteoporotic hip fractures in Iran: a systematic review and meta-analysis.

BACKGROUND: Osteoporosis (OP) is progressively becoming a global concern with the aging of the world's populations. Osteoporotic fractures are associated with significantly increased mortality rates and a financial burden to health systems. This Meta-analysis aims to estimate the annual incidence of osteoporotic fractures in Iran. METHODS: A comprehensive systematic literature search was performed through Medline (PubMed), Embase, Scopus, Web of Science, and Google Scholar to identify studies which contain an investigation of the incidence of osteoporotic fractures in Iran up to December 3rd 2020, with no time and language restriction. For the risk of bias assessments of studies, the Joanna Briggs Institute (JBI) critical appraisal checklist for studies reporting prevalence data was used. The pooled estimation of the incidence of osteoporotic fractures in population aged≥50 years was calculated using random-effects meta-analysis, and the heterogeneity of included studies was quantified with the I2 statistic. RESULTS: In all, 6708 papers were initially retrieved from the electronic databases, among which seven studies were included in the meta-analysis. The pooled standardized annual cumulative incidence of hip fractures was estimated as 138.26 (95% CI: 98.71-193.65) per 100,000 population and 157.52 (95% CI: 124.29-199.64) per 100,000 population in men and women, respectively. CONCLUSION: This study showed a high incidence rate of osteoporotic hip fractures in Iran. Early detection and treatment of individuals with higher risks of primary fragility fractures at primary health care as well as implementing fracture liaison services to prevent secondary fractures are highly recommended. The results suffer from the following limitations: first, a low number of studies that were eligible for inclusion; second, the lack of population-based studies; and presence of highly heterogeneous studies despite the use of a random effect model.

Nationwide population-based surveys of Iranian COVID-19 Serological Surveillance (ICS) program: The surveys protocol.

Background: Serological surveillance of COVID-19 through conducting repetitive population-based surveys can be useful in estimating and monitoring changes in the prevalence of infection across the country. This paper presents the protocol of nationwide population-based surveys of the Iranian COVID-19 Serological Surveillance (ICS) program. Methods: The target population of the surveys is all individuals ≥6 years in Iran. Stratified random sampling will be used to select participants from those registered in the primary health care electronic record systems in Iran. The strata are the 31 provinces of the country, in which sampling will be done through simple random sampling. The sample size is estimated 858 individuals for each province (except for Tehran province, which is 2574) at the first survey. It will be recalculated for the next surveys based on the findings of the first survey. The participants will be invited by the community health workers to the safe blood sampling centers at the district level. After obtaining written informed consent, 10 mL of venous blood will be taken from the participants. The blood samples will be transferred to selected reference laboratories in order to test IgG and IgM antibodies against COVID-19 using an Iranian SARS-CoV-2 ELISA Kit (Pishtaz Teb). A serologically positive test is defined as a positive IgG, IgM, or both. After adjusting for the measurement error of the laboratory test, nonresponse bias, and sampling design, the prevalence of COVID-19 will be estimated at the provincial and national levels. Also, the approximate incidence rate of infection will be calculated based on the data of both consecutive surveys. Conclusion: The implementation of these surveys will provide a comprehensive and clear picture of the magnitude of COVID-19 infection and its trend over time for health policymakers at the national and subnational levels.

Prevalence of Osteosarcopenia and Its Association with Cardiovascular Risk Factors in Iranian Older People: Bushehr Elderly Health (BEH) Program.

Osteosarcopenia is an increasingly recognized geriatric syndrome with a considerable prevalence which increases morbidity and mortality. Although osteosarcopenia is a result of age-related deterioration in muscle and bone, there are many risk factors that provoking osteosarcopenia. These risk factors should be considered by the clinicians to treat osteosarcopenia. We assessed the link between osteosarcopenia and conventional risk factors of cardiovascular diseases. This study was a cross-sectional study that has been conducted within the framework of Bushehr Elderly Health (BEH) program stage II in which participants aged ≥ 60 years were included. Osteopenia/osteoporosis was defined as a t-score ≤ - 1.0 standard deviation below the mean values of a young healthy adult. We defined sarcopenia as reduced skeletal muscle mass plus low muscle strength and/or low physical performance. Osteosarcopenia was considered as the presence of both osteopenia/osteoporosis and sarcopenia. We estimated the age-standardized prevalence of osteosarcopenia for men and women, separately. Using modified Poisson regression analysis, adjusted prevalence ratio (PR) with 95% CI was used to show the measure of associations in the final model. Among 2353 participants, 1205 (51.2%) were women. Age-standardized prevalence of osteosarcopenia was 33.8 (95% CI 31.0-36.5) in men and 33.9 (30.9-36.8) in women. In both sexes, the inverse association was detected with body mass index and having osteosarcopenia (PR 0.84, 95% CI 0.81-0.88 in men and 0.77, 95% CI 0.74-0.80 in women). In both sexes, high-fat mass was positively associated with osteosarcopenia [PR 1.46 (95% CI 1.11-1.92) in men, and 2.25 (95% CI 1.71-2.95) in women]. Physical activity had a significant inverse association in men (PR = 0.64, 95% CI 0.46, 0.88), but not in women. Diabetes was also showed a direct association with osteosarcopenia in men (PR 1.33, 95% CI 1.04-1.69). No associations were detected between the lipid profiles and osteosarcopenia. Results demonstrated a high prevalence of osteosarcopenia in both sexes suggesting a high disease burden in a rapidly aging country. Lifestyle and socioeconomic factors, as well as chronic diseases, were significantly associated with osteosarcopenia.

Incidence patterns of gynecological sarcomas in Iran analysis of National Cancer Registry data between 2009 and 2014.

AIM: Gynecological sarcomas (GS) are rare malignant tumors arising in the female genital organs. Due to the low incidence and diverse histology, information on the epidemiology of these tumors is sparse. We aimed to investigate the incidence rates of GS in Iran that in our knowledge is the first report from Eastern Mediterranean Region. METHODS: In this retrospective study, all malignant tumors with a sarcoma morphology arising in the female genital organs diagnosed between 2009 and 2014 were extracted from the Iran National Cancer Registry dataset. All the cancer cases were categorized according to ICD-O-3 morphologic and topographic codes. Age-standardized incidence rates, age-specific incidence rates, morphologic and geographic distribution of all cases were analyzed and compared with other parts of the world. RESULTS: A total of 1174 cases were diagnosed over the period 2009-2014. The overall age-standardized incidence rate for all sites combined was 6.13 per million females. Analysis of trends in incidence did not show a significant change over time according to annual average percent change analysis (P-value = 0.300). The most common anatomical site was the uterus, accounting for 77% of all cases. The mean (±SD) age at diagnosis, irrespective of tumor site, was 52.3 (±15) years. In terms of morphology, leiomyosarcoma was the most frequently observed subtype, constituting 34% of all GS. Also, the highest ASIR was observed in women aged 60-64 years. CONCLUSION: Based on the findings, GS are relatively rare tumors that occur more in old women. The results of this study provide a comprehensive picture of GS incidence patterns in Iran for more investigation.

Association of fruit and vegetable intake with meal skipping in children and adolescents: the CASPIAN-V study.

BACKGROUND: There are few studies on the association of main meal consumption with fruit and vegetable intake. This study aims to assess the relation between skipping main meals and fruit and vegetable intake in children and adolescents. METHODS: This multi-centric cross-sectional study was conducted in 30 provinces of Iran. This study was conducted in the framework of the fifth survey of a national surveillance program entitled Childhood and Adolescence Surveillance and Prevention of Adult Non-communicable Disease study (CASPIAN- V). 14,440 school students aged 7-18 years were assessed. Logistic regression analyses were used to evaluate the association between frequency of fruit and vegetable intake with skipping main meals. RESULTS: Overall, 14,274 students completed the study (99% participation rate). Their mean (SD) age was 12.3 (3.2) (53% were aged 6-12), 50.6% of them were boys, and 71.3% lived in urban area. In multivariate logistic regression model, statistically significant associations were found between skipping main meals and low fruits and vegetables intake. Skipping breakfast was associated with vegetables intake [OR = 1.19(95% CI 1.02-1.38)] and fruits intake [OR = 5.33(95% CI 4.46-6.37)]. Skipping lunch was associated with vegetables intake [OR = 1.61(95% CI 1.29-1.96)] and fruit intake [OR = 9.11(95% CI 6.55-12.67)]. Skipping dinner was associated with vegetables intake [OR = 1.52 (95% CI 1.15-2.01)] and fruits intake [OR = 2.21(95% CI 1.64-2.97)]. CONCLUSIONS: In this study, low frequency of fruit and vegetable intake was associated with skipping main meals. The results highlight the importance of promoting regular meal consumption with increase in the intake of fruit and vegetables among children and adolescents. LEVEL OF EVIDENCE: Level V.

Socioeconomic inequality of overweight and obesity of the elderly in Iran: Bushehr Elderly Health (BEH) Program.

BACKGROUND: The objective of this population-based, large sample size study was to investigate the socioeconomic inequality of overweight and obesity among the elderly in Iran. METHODS: Baseline data of 3000 persons aged ≥60 years who participated in the Bushehr Elderly Health (BEH) program was analyzed. Overweight and obesity were defined as a body mass index (BMI) equal to or higher than 25 and 30, respectively. Socioeconomic status (SES) was measured by an asset index, constructed using principal component analysis, income, education level, and employment status. The Concentration Index and the Lorenz curve were used to illustrate the levels of inequality for overweight and obesity by gender. RESULTS: The frequencies among men and women were, respectively, 840 (57.7%) and 1131 (73.2%), P < 0.001, for overweight, and 211 (14.7%) and 511 (33.7%), P < 0.001, for obesity. There were direct associations between asset index quintiles and both overweight and obesity among both genders (Ps for trend <0.01) except for obesity among men (P for trend = 0.118). The overall Concentration Indices for overweight and obesity were 0.031 (95%CI = 0.016-0.046, P < 0.001) and 0.041 (95%CI = 0.004-0.078, p = 0.028), respectively. CONCLUSION: Findings support the direct relationship between SES and obesity among women as previously reported in developing countries.

The correlation between insulin-like growth factor 1 (IGF-1) and novel adipocytokines in postmenopausal women: A population-based study.

The adipocytokines and insulin-like growth factor 1 (IGF-1) are involved in insulin resistance, the cardiometabolic syndrome, and atherosclerosis. Therefore, investigating the relationship between circulating levels of the novel adipocytokines and IGF-1 is worthwhile. The correlation between IGF-1, visfatin, and omentin-1 has not been adequately investigated. In a population-based study, 324 postmenopausal women were randomly selected. Circulating IGF-1, visfatin, omentin-1, adiponectin, and high-sensitivity C-reactive protein (hs-CRP) levels were measured with the highly specific enzyme-linked immunosorbent assay method. In multiple regression analyses adjusted for alkaline phosphatase, osteocalcin, and hs-CRP, circulating IGF-1 was significantly correlated with visfatin levels (standardized ß coefficient [ß] = 0.13, partial correlation coefficient [r] = 0.12, p = 0.028). The significant positive correlation between serum IGF-1 and visfatin levels remained after additional adjustments for age and BMI (ß = 0.12, r = 0.12, p = 0.025), metabolic syndrome (ß = 0.13, r = 0.12, p = 0.021), and type 2 diabetes mellitus (ß = 0.13, r = 0.12, p = 0.026). No significant correlations were found between IGF-1, adiponectin, and omentin-1. There is a significant correlation between serum IGF-1 and visfatin levels in postmenopausal women beyond metabolic syndrome, type 2 diabetes, bone formation markers, and hs-CRP levels. The observed correlation between higher circulating IGF-1 and the higher visfatin levels might be a physiological compensation and adaptation to protect against visfatin-induced proinflammatory effects.

Polycyclic aromatic hydrocarbons (PAHs) in coastal sediments from urban and industrial areas of Asaluyeh Harbor, Iran: distribution, potential source and ecological risk assessment.

The distribution and toxicity levels of 16 EPA priority pollutant polycyclic aromatic hydrocarbons (PAHs) in the sediments of Asaluyeh shore, Iran were investigated. The total concentrations of the PAHs in surface sediments ranged from 1,054 to 17,448 ng/g dry weights with a mean concentration of 8,067 ng/g. The spatial distribution of PAHs showed that PAH levels are much higher in the industrial areas in comparison with urban areas. Based on diagnostic ratios, pyrogenic activities were dominant sources of PAHs pollution in sediments comparing petroleum sources. The toxic equivalent concentrations (TEQ Carc) of PAHs ranged from 172 to 2,235 ng TEQ/g with mean value of 997.9. Toxicity levels were evaluated using sediment quality guidelines (SQGs) and toxic equivalent factors. Samples were collected from industrial and urban stations in Asaluyeh shores. According to SQGs, ΣPAHs concentrations in sediments of urban areas were below the ERL (effects range low), but the industrial samples had ΣPAHs concentrations between ERL and ERM (effects range median). Furthermore, ΣHPAHs (heavy PAHs) and some individual PAHs in some industrial stations exceeded ERM, indicating adverse ecological risk effects frequently occur. Findings demonstrate that the surface sediment from Asaluyeh shore is highly to very highly contaminated with PAHs.

Hepatobiliary scintigraphy with SPET in the diagnosis of bronchobiliary fistula due to a hydatid cyst.

In this report, we present the application of hepatobiliary scintigraphy using Tc-99m mebrofenin in the diagnosis of bronchobiliary fistula caused by a liver hydatid cyst, which penetrated the diaphragm. Hepatobiliary scintigraphy noticeably depicted the leakage of the tracer from the biliary system of the liver to the bronchial tree. Hepatobiliary scintigraphy stands as a robust modality in the accurate diagnosis and treatment planning of bronchobiliary fistulas.

Lactational Exposure of Human Infants to Metal (loid)s: A Comparison of Industrial and Urban Inhabitants in North of the Persian Gulf.

In this study, postnatal metal (loid)s (MLs) exposure was compared between the petrochemical and gas area of Asaluyeh (PGA) and urban area of Kaki (UA) in Bushehr province, Iran. Two hundred human breast milk (BM) samples from the industrial and urban areas were analyzed for MLs using Inductivity Coupled Plasma-Optical Emission Spectrometry (ICP-OES). Boron (B), copper (Cu), iron (Fe), and nickel (Ni) were found at the highest levels in both study areas. Adjusted multiple linear regression models revealed that the mean concentration of total MLs in BM samples collected from the PGA was statistically significantly greater than that of the UA (655.85 vs. 338.17 µg/L). Also, the mean concentrations of all detected MLs in BM samples collected from the PGA were statistically significantly higher than those collected from the UA. The hazard index (HI) of combined MLs in the PGA and UA illustrated non-cancer risk for infants. Lead (Pb) and chromium (Cr) in the PGA and Cr in the UA showed the risk of cancer. So it can be concluded that nursing infants from an industrial area are most at risk for MLs exposure during entire lactation course than those from an urban area.

A comparative monitoring of maternal and cord serum polychlorinated biphenyls levels from Iranian pregnant women between industrial and urban areas.

The aim of this study was to compare maternal and fetal exposure to PCBs in pregnant women from a petrochemical and gas area (PGA) and an urban area (UA), by the analyses of serum samples from mother (MS) and cord (CS). After liquid-liquid extracting, samples were analyzed for 12 PCBs congeners by gas chromatography mass spectrometer. Adjusted multiple linear regression models showed the mean levels (µg/L) of total PCBs in the MS and CS samples from the PGA (1.70 ± 0.81 and 1.19 ± 0.43) were significantly higher than those from UA (1.64 ± 0.75 and 1.07 ± 0.38). PCB 44 was predominant in both MS and CS serum samples, and in both PGA (0.80 ± 0.70 and 0.76 ± 0.67) and UA (0.79 ± 0.39 and 0.67 ± 0.34). A negative correlation was found for PCB 52 as one-unit increase in the cord serum levels was associated with 0.024 g decrease in newborn weight. Similarly, one-unit increase in the maternal serum PCB 18 concentrations were associated with 0.09 and 0.086 cm decrease in newborn height and head circumference. The serum levels of PCB 18 and 52 in the mothers who consumed meat and milk at least 1 meal/week were higher than these who consumed meat and milk never or less than 1 meal/month. The findings in this study indicated that higher maternal exposure to PCBs, as result of living in an industrialized area, leads to higher PCBs accumulation in cord blood, which consequently passes to the developing fetus. These events may cause harmful effects on both them in-utero and afterbirth growth and development.

Vaccination effects on reducing COVID-19 complications in pregnancy: A large-scale report from Iran.

OBJECTIVE: The objective of this study was to evaluate the effects of maternal coronavirus disease 2019 (COVID-19) vaccination on preventing severe complications of COVID-19 in pregnant women. METHODS: A retrospective study was conducted in pregnant women infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during pregnancy and/or for up to 6 weeks postpartum between September 1, 2021, to January 30, 2022. The data was retrieved from a national database. The pregnant women were divided into two groups of vaccinated and unvaccinated. The proposed outcomes (the need for hospitalization, intensive care unit admission, and mechanical ventilation and products of conception complications) were compared between the two groups. RESULTS: Approximately 90 000 pregnant women infected with COVID-19 were included in the study. The data of the vaccinated (19 922) and unvaccinated (70 147) groups were analyzed and compared. Pregnant patients in the vaccinated group had a significantly lower rate of hospitalization (21.2% vs 29.4%) (odds ratio [OR], 0.648 [95% confidence interval (CI), 0.625-0.673], P = 0.0001) and intensive care unit admission (3.7% vs 7.8%) (OR, 0.453 [95% CI, 0.382-0.535], P = 0.0001). The need for mechanical ventilation was also lower, although not statistically significant, in the vaccinated group than in the unvaccinated group (30 of 155 [19.4%] vs 418 of 1597 [26.2%]) (OR, 0.677 [95% CI, 0.448-1.024], P = 0.063). Cesarean section (54.3% vs 58.1%) (OR, 0.856 [95% CI, 0.751-0.977], P = 0.021) and stillbirth (0.4% vs 3.6%) (OR, 0.097 [95% CI, 0.026-0.252], P = 0.0001) were also significantly lower in the vaccinated patients. Most pregnant women in the vaccinated group (18 484-96.14%) received Sinopharm BIBP COVID-19 inactivated vaccine. No significant differences were seen in the effect of different types of COVID-19 vaccines on reducing COVID-19 complications in infected pregnant patients. CONCLUSION: Maternal COVID-19 immunization is effective in reducing COVID-19 complications in infected pregnant women.

Management goal achievements of diabetes care in Iran: study profile and main findings of DiaCare survey.

Aim: This paper presented the methodology and main findings of a population-based survey to determine diabetes care status among type 2 diabetic subjects in Iran. The current study assessed treatment goal achievements in type 2 diabetics, diabetes care service utilization, prevalence of diabetes complications, and psychological effects of diabetes in a representative sample of Iranian population in urban and rural areas. Materials and Methods: This nationwide study was conducted between 2018 and 2020 as the observational survey entitled "Diabetes Care (DiaCare)". We studied a representative sample of participants with type 2 diabetes, aged 35-75 years, living in urban and rural areas in all thirty- one provinces of Iran. Data were collected by an interviewer in a form of a questionnaire that includes demographic and socioeconomic status, family and drug history, lifestyle, and self-reported psychological status according to a Patient's Health Questionnaire (PHQ). Management goal achievements, diabetes care service utilization, diabetes complications and psychological effects of diabetes were also assessed. Physical measurements were measured based on standard protocol. Fasting blood glucose (FBG), HbA1c, lipid profile, and also urine albumin to creatinine ratio were obtained from all participants of the study. Results: Overall, 13,334 people with type 2 diabetes in 31 provinces of Iran completed the survey (response rate: 99.6%). In total 13,321 participants, 6683(50.17%) women and 6638(49.83%) men were included in our analysis. Thirteen recruited patients refused after the consenting process and did not respond. The mean age (SD) of total participants was 54.86 ± 9.44 years and 71.50% were from the urban areas. 13.66% of diabetic patients had achieved the triple target of management [controlled HbA1c, blood pressure, and Low-Density Lipoprotein-Cholesterol (LDL-C)] in the whole country. While 28.74% of people had controlled HbA1c and 33.40% of them had controlled FBG. Diabetic subjects living in rural areas had less controlled HbA1c (23.93 vs. 29.48), controlled FBG (29.50 vs. 34.20) and controlled triple targets (10.45 vs. 14.32) than those living in urban areas. Diabetic neuropathy and diabetic foot were more common in women than men, while end-stage of renal disease (ESRD) was more common in men than women. Conclusions: This population-based study provided representative information about diabetes care in Iran. The high prevalence of diabetes and low proportion of diabetes control in Iran implies that it is necessary to identify factors associated with poor treatment goal achievements. Besides, general improvements in management and care of diabetes are mandatory.

The Iranian National Blood Pressure Measurement Campaign: What Do the Process and Output Evaluation say?

BACKGROUND: The Iranian National Blood Pressure Measurement Campaign (INBPMC) was conducted all over the country to raise awareness in different groups of people regarding the importance of blood pressure and persuading them to manage their blood pressure. The present research aimed at assessing the process and output of this campaign. METHODS: For process evaluation, 31 universities/faculties were selected. Experts from the Ministry of Health and Medical Education assessed the documentation of the campaign implementation using the designed checklist. The output was assessed by including 8274 people and through a telephone survey using the designed instructions. RESULTS: The response rate of the telephone interviews was 82.74% (8274 people). It was found that 79% of the selected groups were aware of the INBPMC. Among them, 64% remembered the messages, 99% of the participants who remembered the messages agreed with those messages, and 89% of the participants who agree with the messages went for a measurement of their blood pressure. In the telephone interviews, 30% of the participants stated that they were diagnosed with hypertension, 97% of these participants received the required consultations for subsequent care, and 86% of them went to the health service centers to receive care. The process evaluation of the INBPMC indicated that the universities of medical sciences obtained 97% of the score of the checklist. CONCLUSION: The INBPMC was successful and accomplished its objectives.

Thoracic Sarcoma: A New Glance at the Epidemiological Characteristics of Disease in Iran from 2009 to 2014.

Background: The heterogeneity, high rate of mortality and lack of comprehensive diagnostic methods have categorized primary sarcomas of the thorax as a malignancy with dismal outcomes and unknown etiology. Given the fundamental role of epidemiological analysis in establishing management strategies, we designed a study with focus on the epidemiological characteristics of primary thoracic sarcomas in Iran. Methods: This national population-based cancer study was conducted on patients with histologically confirmed sarcoma of the thorax referred to the Iranian National Cancer Registry between 2009 and 2014. The incidence was calculated as number of cases per 100,000 person-years and was age-adjusted by the direct method using the weight of the 1960 world standard population. Results: Over a 6-year period, 1477 cases with pathologically confirmed thoracic sarcomas were registered in Iran, of which 896 were male and 581 were female. Khuzestan Province had the highest incidence of thoracic sarcomas as compared to other provinces. Malignant mesothelioma was the most common histological subtype (20.85%). Moreover, the age-standardized incidence rate (ASR) of the disease was 1.94 per 100,000 which was more common in males than females with the highest incidence rate in men aged more than 65 years. Conclusion: Our study provided valuable epidemiologic data on characteristics of thoracic sarcomas. This data can be used for strategizing preventive measures.

Maternal and fetal exposure to metal (loid)s, maternal nutrition status, and impact on prenatal growth in an energy rich zone and an urban area along the Persian Gulf.

The main purposes of the study were to determine whether maternal and cord blood (MB and CB) levels of metal (loid)s (MLs) are different between industrial and urban areas. Subjects were derived from the petrochemical and gas area (PGA) of Asaluyeh County and the urban area (UA) of Bushehr County in Iran. Adjusted models revealed significant differences between the PGA and UA for maternal Fe, Cu, Mg, Cd, Zn, Ni, V and Pb levels, likewise cord Cu, V, Pb and Ni levels, which were higher in the PGA. Unadjusted models revealed there were decreases in neonatal weight and head circumference by 16.550 g and 0.059 cm, respectively for each Ln unit increase in maternal Cr levels. The mean blood levels of MLs significantly associated with food consumption frequency. The MLs were detected at higher levels in the body's fetuses and their mothers who resided in the PGA than those from the UA. So, the fetuses of mothers living in an industrial areas may be at higher risk from anthropometric measures. The impact of prenatal exposure to MLs on prenatal growth should be considered for better understanding in the further studies.

Socioeconomic difference in physical activity in children and their parents: The childhood and adolescence surveillance and prevention of adult noncommunicable disease study.

Background: As a health-related behavior, physical activity (PA) differs according to individual's socioeconomic status (SES). This study aimed to assess the socioeconomic difference in leisure-time PA among Iranian students and their parents at national and regional levels. Study Design: Nationwide cross-sectional study. Methods: This study was conducted as part of a national survey conducted in 2015 among 14400 Iranian students and their parents. Total PA level was measured as the average hours spent on PA per week. Nonlinear principal component analysis was used to construct the households' SES based on household's assets, type of house ownership, occupation of fathers and the educational levels of fathers and mothers. Concentration index was applied to measure the inequality in the PA level in parents and students. Results: Complete data of 13313 students and their parents were available. At the national level, students spent more hours of PA per week (3.753 h per week [h/w]) as compared to their parents. Moreover, PA h/w was higher in fathers (3.488 h/w) as compared to mothers (2.763 h/w). The lowest means of mother's and student's PA were found in the highest SES region. At national level, the concentration indices (CI) of father's and mother's PA were -0.050 (95% CI = -0.067 ~ -0.030) and -0.028 (95% CI = -0.044 ~ -0.012), respectively, indicating pro-poor inequality, but the CI value of student PA was non-significant (CI = -0.007, 95% CI = -0.023-0.008). Conclusions: Given that the mother's and student's PA level was low in the high SES regions, it is suggested that focused PA planning may further increase the level of PA across higher SES regions and might be effective in reducing the PA inequality.
